The series addresses the kernel warnings reported by Johan at [1] and are are required to X1E cpufreq device tree changes to land. It also proposes addition of quirks to bypass a fw bug on X1E devices.

These are the only freqs that appear as duplicates and will be fixed with a firmware update. FWIW the warnings that we are addressing in this series will also get fixed by a firmware update but they still have to land for devices already out in the wild. V5: * Drop all the patches that have already landed upstream and mark the series as RFC to get feedback on adding quirk support for the perf protocol. V4: * Rework debugfs node creation patch [Ulf/Dmitry] * Reduce report level to dev_info and tag it with FW_BUG [Johan/Dmitry] * Add cc stable and err logs to patch 1 commit message [Johan] V3: * Pick up R-b, T-b from the list. * Pick up the updated patch from Cristian for skipping opps. * Update device names only when a name collision occurs [Dmitry/Ulf] * Drop Johan's T-b from "fix debugfs node creation failure" * Move scmi_protocol_msg_check to the top [Sudeep] V2: * Include the fix for do_xfer timeout * Include the fix debugfs node creation failure * Include Cristian's fix for skipping opp duplication V1: * add missing MSG_SUPPORTS_FASTCHANNEL definition. base: next-20250225 Sibi Sankar (2): firmware: arm_scmi: Ensure that the message-id supports fastchannel firmware: arm_scmi: Add quirk to bypass SCP fw bug drivers/firmware/arm_scmi/driver.c | 75 +++++++++++++++------------ drivers/firmware/arm_scmi/perf.c | 30 ++++++++--- drivers/firmware/arm_scmi/powercap.c | 8 +-- drivers/firmware/arm_scmi/protocols.h | 4 +- 4 files changed, 72 insertions(+), 45 deletions(-) -- 2.34.1
